By adding historically accessed data to the cache server, the data in the cache server can be read faster than the data in the business server.

At present, the web server takes the Uniform Resource Locator (URL) sent by the client as a key, and sends the URL to the service server, and the web server receives the return result corresponding to the URL sent by the service server, and returns the result. As a value, the key-value is stored in pairs in the cache server. When the key-value is paired to the cache server, the web server sets the expiration time of the key-value, as long as the client sends the next request information about the key within the expiration time, the web server. The value corresponding to the key is obtained from the cache server, and the value is sent to the client to reduce the load of the service server and reduce the response delay of the client.

The service server identifies different data values by the data ID. However, when the data value corresponding to the data ID in the service server changes, if the client sends the request information about the key within the expiration time, the data value obtained by the client is still the old data value stored in the cache server. For the same key, and during the expiration time of the cache server, the update of the data value of the service server and the update of the data value in the cache server are not updated synchronously, that is, the real-time value of the data stored in the cache server is poor, resulting in poor performance.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention provides a method for updating cache data, which is applied to the service server side. As shown in FIG. 1 , the method includes:

101. The service server sends the response data corresponding to the data request information to the web server according to the data request information sent by the web server, and establishes a mapping relationship between the keyword key and the data ID.

In the embodiment of the present invention, the association relationship between the client, the web server, the cache server, and the service server will be described in detail by way of example. Exemplarily, as shown in FIG. 2, the figure includes N clients and N cache servers, where N is a positive integer greater than 2; the client is based on HTTP-Hypertext transfer protocol (HTTP). The web server sends data request information, where the data request information includes a Uniform Resource Locator (URL). After receiving the data request sent by the client, the web server generates a keyword key according to the URL, and based on the keyword, The key sends the response data value corresponding to the keyword key to the cache server. If the response data value corresponding to the keyword key exists in the cache server, the response data value is obtained, and the response data value is sent to the client; if the cache server is If the response data value corresponding to the keyword key does not exist, the web server sends the data request information to the service server, where the data request information carries the keyword key, and after receiving the data request information sent by the web server, the service server Asynchronous processing, the asynchronous processing includes: performing data request information Should the information corresponding to the data request sent in response to the data value of the web server, and establishing a mapping relationship between key data and key ID.

The data request information includes the keyword key, and the keyword key is generated by the web server, and after receiving the response data value, the web server sends the keyword key and its corresponding response. The data value is stored in a cache server, and the data ID is a unique identifier of the service server storing the response data value.

It should be noted that the data ID and the keyword key have a one-to-one mapping relationship, and the mapping is The system is stored in the service server, and the keyword key and the response data value are also in a one-to-one correspondence, which is stored in the cache server, and the web server, the cache server, and the service server can communicate with each other. In the embodiment of the present invention, if the response data value corresponding to the keyword key is stored in the cache server, it indicates that the response data value is consistent with the response data value corresponding to the data ID in the service server, that is, the response data value is the latest. Response data.

Optionally, the web server can communicate with the plurality of cache servers, wherein the cache server is a distributed cache server, and can respond to the data request information sent by the client in time. In order to reduce the load of the cache server, determine the timeliness of the cache server response data request information. Before the web server saves the keyword key to the cache server, the web server encrypts the keyword key, and the encrypted keyword key is a random character. The string server stores the keyword key randomly in the cache server, which improves the dispersibility of the keyword key and reduces the load on the cache server due to the excessive concentration of the keyword key. The encryption of the keyword key and its corresponding data value may be implemented by, but not limited to, the following implementation manners, for example, a hash algorithm hash, including a message digest algorithm (MD5), and a specific embodiment of the present invention. The implementation algorithm is not limited.

It should be noted that although the keyword key is generated according to the data request information, since the keyword key is encrypted and is irreversible, the purpose is to reduce the load of the cache server, and therefore, the web server is When the service server sends the data request information, if only the keyword key is sent, the service server cannot identify the specific data request information in the keyword key, and cannot respond to the web server. Therefore, the web server requests data from the service server. When you need to carry the keyword key into the data request information.

Exemplarily, if the data request information sent by the client includes the URL: http://api.lesports.com/sms/v1/matches/28845003? Caller=1001, the web server has the most keyword key, and performs MD5 encryption operation on the keyword key. The encrypted keyword key is: 9afbd22506aff85cc6dd395a57b1471d, and the encrypted keyword key of the web server is added to the data request information. The service server sends the information to the service server, so that the service server can establish a mapping relationship with the data ID according to the keyword key.

102. The service server monitors whether the response data corresponding to the data ID is updated.

In the embodiment of the present invention, the data ID in the service server is not updated, but the data ID is The corresponding response data value is updated at any time, and the update change time is random. Therefore, the service server needs to monitor the response data value corresponding to the data ID to determine whether the response data value corresponding to the data ID is updated. .

103. If it is determined that the response data corresponding to the data ID is updated, the service server acquires the keyword key based on the mapping relationship, and deletes the keyword key and the corresponding response data in the cache server.

If the value of the response data corresponding to the data ID is not updated when the service server performs the step 102, if the response data value is stored in the cache server, the value of the response data in the service server is consistent with the value of the response data stored in the cache server. Therefore, there is no need to actively invalidate the response data value in the cache server, and the active failure is to actively delete the response data value in the expiration time of the response data value in the cache server. If the value of the response data corresponding to the data ID is updated by the service server when the step 102 is performed, if the value of the response data is stored in the cache server, the value of the response data in the service server is inconsistent with the value of the response data stored in the cache server. Therefore, the response data value in the cache server needs to be actively invalidated, so that the response data value obtained by the client user is real-time updated data.

The active invalidation of the response data value in the cache server by the service server includes: first, the service server searches for and determines the keyword key corresponding to the data ID according to the mapping relationship between the keyword key and the data ID established in step 101; The response data value corresponding to the keyword key is obtained according to the keyword key; finally, the keyword key and its corresponding response data value are deleted. When the client sends the data request information corresponding to the keyword key again, the web server re-stores the keyword key and the corresponding response data value in the cache server.

It should be noted that, in the embodiment of the present invention, after receiving the response data value sent by the service server, the web server stores the <keyword key, the response data value, and the expiration time expire> in the cache server, where The expiration time expire is set by the web server. If the service server does not update the response data value within the expiration time expire, when the client sends the data request information with the keyword key, the web server obtains the response data value from the cache server. And send it to the client; in the cache server, when the expiration time expire is reached, the cache server will delete <keyword key, response data value, expiration time expire>. Exemplarily, the web server will <keyword key, response data value, expiration time expire at 10:00. Stored in the cache server, wherein the expiration time expire is set to 10 minutes; when the web server receives the data request information carried by the client 1 and carries the keyword key at 10:01, the web server obtains the keyword from the cache server. The response data value corresponding to the key is sent to the client 1; when the web server receives the data request information carried by the client 2 and carries the keyword key at 10:30, the web server sends the key to the cache server to obtain the key. The response data value corresponding to the word key, and the returned response data value is empty. At this time, because the expiration time expire is exceeded, the cache server deletes the <keyword key, response data value, and expiration time expire>, therefore, the cache server does not Save <keyword key, response data value, expiration time expire>.

The method for updating the cached data provided by the embodiment of the present invention, after receiving the data request information sent by the web server, the service server asynchronously processing the request information, including: sending the response data value corresponding to the data request information to the web server And establishing a mapping relationship between the keyword key and the data ID, wherein the data request information includes a keyword key, and the keyword key is generated by the web server, and when the web server receives the response data value, the keyword key And the response data value is stored in the cache server, the data ID is a unique identifier of the service server storing the response data value; the service server monitors whether the response data value corresponding to the data ID is based on the mapping relationship between the established keyword key and the data ID. Update, when it is determined that the response data value corresponding to the data ID is updated, the keyword key is obtained based on the mapping relationship, and the keyword key and its corresponding response data value are deleted from the cache server, so that the response data value in the cache server is implemented. Active failure; compared with the prior art, the present invention In the example, the mapping relationship between the data ID and the keyword key is established, and the response data value corresponding to the data ID is monitored in real time to ensure that the response data value obtained by the client user is the real-time updated response data value, so as to improve the client. The end user obtains the accuracy of the response data value, thereby improving the user experience of the client user.

Further, as a refinement and extension of the foregoing embodiment, the mapping relationship between the keyword key and the data ID is established in step 101, which may be implemented by using, but not limited to, the following manners:

Manner 1: The service server obtains the data ID from the data request information, and establishes a mapping relationship between the keyword key and the data ID.

The data request information sent by the web server includes a URL, and the data ID may exist in the URL. Therefore, when the service server establishes a mapping relationship between the keyword key and the data ID, the service server parses the data request information and obtains It contains the URL and determines the URL Whether there is a data ID in the middle, if there is a data ID, the data ID is obtained, and a mapping relationship between the data ID and the keyword key is established.

Exemplarily, according to the above example, the data request information sent by the client includes the URL: http://api.lesports.com/sms/v1/matches/28845003? Caller=1001, and the encrypted keyword key is: 9afbd22506aff85cc6dd395a57b1471d, and the service server determines that the data ID in the URL is 28845003. The above is only an exemplary example, and the content of the URL, the format parameter included in the URL, and the encrypted keyword key are not specifically limited in the embodiment of the present invention.

In the embodiment of the present invention, the mapping relationship between the established data ID and the keyword key is stored in the redis database. For example, as shown in Table 1, Table 1 shows the redis database provided by the embodiment of the present invention. The mapping between the storage data ID and the keyword key is not limited. The specific implementation manner and storage format of the mapping relationship between the data ID and the keyword key are not limited in the embodiment of the present invention.

Table 1

Manner 2: The data ID is obtained from the response data value corresponding to the data request information, and a mapping relationship between the keyword key and the data ID is established.

In the service server, the data ID and the response data value are in one-to-one correspondence. Therefore, the service server obtains and determines the data ID carried in the response data value by parsing the response data value, and establishes a relationship between the keyword and the data ID. The mapping relationship, wherein the mapping between the keyword key and the data ID is established by the service server, and the storage of the mapping relationship, refer to the related description of the foregoing manner 1. The present invention does not establish a keyword with the service server. The mapping relationship between the data IDs and the storage of the mapping relationships are described in detail.

Further, when the service server updates the response data value corresponding to the data ID, the editor of the response data value edits the response data value, and after editing the response data value, clicks the preset update component to implement the response data. Update of value. From the technical implementation level, the service server receives the response when it receives the editor's click on the preset update component. When the data value update instruction is executed, the update response data value is executed. Therefore, in the embodiment of the present invention, the service server can determine whether the response data value corresponding to the data ID is updated by monitoring the preset update component. The preset update component of the embodiment of the present invention may be different due to different programming languages of the service server. Specifically, the preset update component may be a save component, an update component, a replacement component, etc., and the specific embodiment of the present invention. The preset update component is not limited.

Further, the keyword key and its corresponding response data value are stored in the cache server, and the keyword key and the data ID are stored in the service server, and the service server performs the deletion of the cache server according to the keyword key. When the keyword key and the corresponding response data value thereof are used, the preset function interface is invoked to establish an interaction relationship with the cache server, and the keyword key is obtained from the cache server based on the keyword key recognized by the cache server and the service server. The corresponding response data value is deleted by the keyword key and its corresponding response data value. When the keyword key and its corresponding response data value are deleted, first, the service server determines the field storing the key key in the cache server according to the keyword key; secondly, in the traversal manner, and finally determines the keyword in the keyword key field. The keyword key and its corresponding response data value are deleted and deleted. The specific implementation manner of deleting the keyword key and the corresponding response data value in the cache server of the service server is not limited in the embodiment of the present invention.
